They found that the warming in the data - sparse regions was progressing faster than the global average (especially during the past couple of years) and that when they included the data that they derived for these regions in the computation of the global average temperature, they found the global trend was higher than previously reported — just how much higher depended on the period over which the trend was calculated.

The main idea is that the existing compilations of the global average temperature are very data - sparse in the high latitudes.
